The tacker has a plunger case 10, Fig. 1, with a lateral projection 11, to which is secured a raceway 14. A spring-raised plunger 15 is attached to the driver 19 by a cylindrical part 23, in a socket 25, which form a, joint with sufficient play to permit alignment of the plunger with the throat. The plunger case 10 is cut away at its lower end to accommodate a throat block 27 cooperating with the separator 31 pivoted to it at 37 by the hook 35 and held in position by a spring 47. The raceway is extended at its lower end to reach an opening in the throat block, points 49, Fig. 5, supporting the tacks till they reach the throat. Other parts 51, 53 on the raceway restrain lateral movement of the shanks of the tacks. The tacker has the usual nozzle 61 and a hook 12 on the raceway for attachment to another raceway, not shown, by which it is supplied with tacks. A cam on the second raceway raises a detent 16 on the raceway 14 to allow the passage of tacks. The detent 16 acts as a tack retainer when the loading raceway is removed. On the descent of the driver 19, a tack held at the bottom of a groove 43, Fig. 4, in the separator is engaged and driven. Towards the end of the stroke the cam 21 engages the groove 45 in the separator and rocks it to allow a tack to escape from the raceway and impinge against the driver. On the upstroke of the driver the groove 55, engages the head of the tack and inclines its shank towards the driver so as to allow a finger 39 on the separator to move between that tack and the next. On the top of the stroke the separated tack falls to the bottom of the groove 43, in the separator.

[Also in Group XXXIX] In a system in which a radio transmitter is automatically connected to the appropriate programme source (e.g. studio) for each successive programme during the day, the setting of the connecting switch is controlled by a control uniselector which is caused to advance its wipers one step at the end of each unit of time throughout the period. As described, certain of the wipers of the control uniselector are permanently wired to different relays respectively of a set of six relays and at least one of the wipers is connectable to ground. In each angular position in the banks of the control uniselector certain of the bank contacts, including that associated with the said one wiper, are connected together by the insertion between the wiring tags of the bank of a connecting device which makes contact with the tags corresponding to the desired contacts through bowed resilient strips forming the teeth of a comb-like metal member. This metal member is insulated from the undesired tags of the position under consideration and from all the tags of the adjacent position. Thus in each position of the wipers a combination of the relays will be connected to the said one wiper. It is arranged that the control uniselector is stepped once every fifteen minutes and that shortly before it is stepped, ground is applied to the said one wiper to actuate the combination of relays. These relays mark the position in the banks of the connecting appropriate to the programme source for the next fifteen minute period and the connecting switch is thus driven to that position to effect the desired connection.
